Chen loves the motherland and has lofty national integrity. He loves the * * * production party and socialism, and often says, "I agree with the proposition of the * * * production party." Although he has experienced many political movements and suffered shocks, he has not shaken his belief in the * * * production party and socialism. 1962 attended the Guangzhou conference, and he was very happy to hear that the party and state leaders affirmed that he was not a bourgeois intellectual. On 1963, he applied to join the China * * * production party. The Party Committee of Hangzhou University thinks that he has an innocent history and lofty aspirations, and he should be accepted as party member, and the provincial party committee agrees. The following year, the party branch meeting passed his application, and the higher party Committee also approved it. Later, it was shelved for some reason, but he worked hard as always to train a new generation of mathematicians for the country.

Chen has always been straightforward, willing to tell the truth, but also dare to tell the truth. In the field of mathematics, several waves of denying the necessity of basic theory have hit him, and he can confidently refute it. He believes that mastering theory can make people stand tall and see far. Practice is very important and theory is indispensable. He thinks it is useless to talk about basic theory alone. Some basic theories may not be used for the time being, but they may be used in a few decades. For example, imaginary numbers seem to be useless when they first appeared, and they have been criticized by some people. After hundreds of years, it has been widely used in mechanics. At that time, he didn't applaud the Great Leap Forward in society, and he didn't plan for the Red College. He just didn't write the sentence "Only specialized but not red". During the Cultural Revolution, he was worried about the future of mathematics in China. He wrote to Mr. Zhou, asking about the future of mathematics, and eager to make greater contributions to the country in his lifetime. He has been indifferent to fame and fortune all his life and has an open mind. Every time he mentions his peers, he always looks at his shortcomings longer than others, and often asks students to "have one's own self, which is the foundation of virtue."

Chen is an effective educator. He always advocates that teaching and scientific research complement each other and promote each other. He often said that to teach books well, we must rely on scientific research to improve them; On the other hand, if you don't teach, you can't train talents and scientific research can't be carried out. He followed this principle all his life. He attaches great importance to teaching and compiles new speeches every year. He also said that attending classes is like fighting, so we should be fully prepared. Every time we talk about a new content, we always explain the ins and outs of the problem. When introducing literature, some problems worth studying are often raised. When guiding graduate students, he always lets students master the latest literature and get close to the forefront of the subject as soon as possible. This culture method is effective. There are many students who work for him, and there are more than 40 graduate students directly under his guidance. Most of them become professors of mathematics, and some of them are famous in the world. Chen Yisheng works hard, keeps forging ahead and innovating. He published more than 60 mathematical papers in academic journals at home and abroad, and translated 9 monographs, which made immortal contributions to the development of mathematical research in China.

Chen's life is a life of burning himself and illuminating others. Both a scholar and a man set an example for future generations. People remember him and respect him. He is one of the founders of modern mathematics in China.
